As Ryu nodded and created some distance between the two and threw some shurikens at Sakumo and said,
"Katon: phoenix sage flower crimson nail"
Sending blazing shurikens at the jounin who countered it by saying,
"Doton: earth style wall"
And blocked the incoming blazing shurikens before Ryu appeared just behind Sakumo in mid air taking a jump and aiming a kick at the jounin who blocked the kick and punched Ryu in the chest which Ryu managed to sidestep only to be kicked right In the chest which Ryu managed to block by crossing his arms in front of his chest although the uchiha skidded away a lot bit and there was eminent pain his arms.
As Ryu looked at Sakumo and send chakra to his eyes to activate his sharingan which glared at Sakumo who upon seeing a fully matured sharingan on a five years old was shocked as he was not made aware of Ryu's sharingan by Kagami and the jounin knew that the battle was just beginning.
Just then Sakumo saw his surroundings changing and the ground beneath his feat cracking with dark hands coming out of the cracks to grab onto Sakumo's leg who quickly surged his chakra and broke the sharingan genjutsu and reminded himself not look in Ryu's sharingan to avoid unnecessary problems.
As Sakumo broke the sharingan genjutsu and came back to his senses only to see Ryu standing there going through handseals at an impeccable speed and say,
"Futon: wind cutter technique"
Sending a fast and invisible sharp wind towards Sakumo who too performed some handseals to protect himself the most offensive of the five elements and said,
"Doton: bedrock coffin"
And surrounded himself with thick multiple layers of rocks on which the wind cutter left quite an impact on.
On lowering the rocks Sakumo saw multiple explosion tagged kunais hurling towards him while Ryu was nowhere to be seen, seeing this Sakumo bieng an adept sensor, quickly sensed out Ryu hinding behind one the trees and quickly vanished in a shunshin to stand right besides Ryu and punched the astonished uchiha who was sent hurling away to the middle of the field before Sakumo said,
"Suiton: Water dragon bullet"
And from the pond just few metres behind Sakumo, a large water dragon with yellow eyes arose and darted towards Ryu who narrowed his sharingan eyes at the incoming water dragon and went through handseals saying,
"Katon: Fire dragon bullet"
And spitted out a equally large fire dragon , as the two dragons coiled around each other before colliding and creating a viel of steam in the training ground but seeing it was not thick enough to hinder his sharingan Ryu quicked threw couple of shurikens at Sakumo who easily deflected them with his own kunai only for Ryu to say,
"Katon: Dragon fire technique"
As fire rushed along the ninja wires attached to the shuriken towards Sakumo who only smiled at this and said,
"Suiton: Stormy blockade"
As large amounts of water fell from the sky in front of Sakumo effectively extinguishing the fire befored rushing at Ryu who used kawarami to get to safety and said,
"Raiton: False darkness"
Sending three large lightning spears at high speeds towards Sakumo who quickly said,
"Doton: earth style rampart"
Making the a huge and thick wall of earth emerge from underneath jounin's feet which dispersed the lightning spears before Sakumo jumped back down and said palcinv his hands on the ground,
"Doton: Flying thrown stones"
Seeing the large amounts of rocks hurling towards him Ryu went through handsigns and said
"Futon: Spiralling wind ball"
And fired multiple small yet immensely powerful balls of wind at the incoming rocks in rapid succession while using his sharingan in conjunction to avoid the stray rocks.
Seeing Ryu block his earth style attack Sakumo quickly appeared a couple meters behind Ryu and hurled multiple kunais at Ryu's back who slightly glanced back while finishing off with the rocks and flipped in air while using his sharingan avoided all the kunais before saying,
"Raiton: Lightning rat violent quake"
As small yet sharp and quick lightning discs rushed at Sakumo, the jounin also went through handsigns saying,
"Doto:Earth dragon bullet"
As a dragons head made up of mud emerged from the ground and fired multiple mud balls at the lightning disc forcing them to disperse, seeing this ryu frowned while wiping the sweat on his forehead knowing the toll all the ninjutsu has taken on his chakra reserve which had depleted by 40%.
As Ryu sighed before sending chakra to the storage seal on his left wrist from which a tanto appeared in a puff of smoke making Sakumo raise a brow before smirking slightly afterall kenjutsu was Sakumo's speciality and so the jounin too took out his trusted tanto from his back which he had named the white fang.
As both got into thier stance before rushing at each other at high speeds, as the streaks of white and black collided both the blades met each other and due to his sharingan Ryu could see small cracks appearing on edge of his tanto just from one clash and he thought,
'This can't be a ordinary blade it'll foolish to continue in a kenjutsu battle I'll only end up losing my blade'
Making his decesion Ryu made a single handsign thinking,
'Katon: great fireball jutsu'
And hurled a humongous fireball at Sakumo who quickly used kawarami jutsu and created distance.
Seeing the opportunity Ryu quickly sealed his tanto back into his wrist before saying,
"Katon: Fire stream"
Spitting a narrow amount of fire which expanded to a large sheet of fire while moving towards Sakumo who countered saying,
"Suiton: Exploding Water Colliding Wave"
Spitting a great volume of water from the mouth, extinguishing the fire and continued to go through handseals saying,
"Doton: Earth Flow Spears"
Sensing the movement under his feet Ryu quickly jumped in air and used shunshin to appear a couple meters away before the earth spears could pierce him, and quickly said going through handseals,
"Futon: Beast tearing gale palm"
And send a huge wind hand from his own palm towards Sakumo who quickly dodged the violent jutsu only for Ryu to appear at his side and aim a wind blade encased palm at the jounin's chest, seeing this Sakumo replaced himself with a wood log which was sliced in half and appeared at a safe distance before taking out the white fang which started to glow white much to Ryu's confusion and amazement before Sakumo slashed the white fang at him from which a glowing cresent arc rushed at him as he quickly ran through handseals and said,
"Futon: Swift wind wall "
As thick winds started to revolve around himz as the wind and attack met, his wind wall managed to soften Sakumo's attack but he was flunged in the air before crashing into a tree.
As Ryu got up he did feel some pain in his back which he ignored and then assessed his condition, he had cuts and burns all of his clothing and was bleeding a little from the mouth, he quickly created a shadow clone while looking at a perfectly fine Sakumo looking at him , as both went through handseals and said in unison,
"Futon: Pressure damage"
"Katon: Flame Whirlwind"
This combination jutsu was the strongest in his arsenal and used a lot of chakra creating a humongous hemisphere of rotating raging fire dome moving towards Sakumo at high speeds destroying everything in its path. Seeing this jutsu Sakumo's eyes widened a little bit deducing it as a high A rank jutsu before going to action and saying,
"Suiton: Great Waterfall Technique"
Spitting large amounts of Spiralling water from the mouth effectively extinguishing the fire wind combination jutsu.
As the jutsu's ended Sakumo saw a slightly panting Ryu calmy walking towards him seeing this he knew ryu didn't have an intention to fight anymore and all in all Sakumo was really speechless with Ryu's performance afterall a 5 year old hurling A and B rank jutsu of three different elements one after another could only be taken as a joke and couldn't help but think to himself,
'I can see what you meant when you said that he would shape the future of the hidden leaf village and the Shinobi world'
As you went and stood in front of Sakumo who just nodded at and said to him with a kind smile,
"You performed beyond my expectations Ryu, now I really think you might just be able to achieve your dream"
As Ryu just shook his head at the praise and reply to the powerful shinobi standing in front of him,
"Im nowhere near your level Sakumo sensei I still have ways to go if I want to be the strongest"
Making Sakumo laugh a little and nod at him while and think,
'It does feel nice to be called sensei perhaps I can get used to it'
Before Sakumo looked at Ryu seriously and asked,
"Today you can rest, but from tomorrow onwards we would start your training and would take small missions first are you ready Ryu?"
To this Ryu just gave Sakumo a confindnet smirk and replied with a tone of determination,
"I am always ready sensei"
